PAVING-TILES.

SPECIFICATION forming part of Letters Patent No. 739,345, dated September 22, 1903.

Application filed April 16 1902. Serial No. 108,076. (No model.)

To all whom it may concern.-

Beit known that I, ADOLPHE PIOHA, manufacturer, a subject of the King of'Belgium, residing at 54 Boulevard Lousbergs, Ghent, in the Kingdom of Belgium, have invented certain new and useful Improvements in Paving-Tiles, of which the following is a specification.

This invention relates to the manufacture of tiles for forming pavements, and relates more particularly to the manufacture of tiles, for producing the efiect of tessellated work or mosaic.

The object of the invention is to obviate in pavements of this kind the production of visible joints, which by uniformly cutting the design which the pavement is intended to form are very much in evidence and prej udicially affect the appearance of the design.

The invention consists, essentially, in imparting to the tiles irregular contours or edges, thus producing projections andindentations following the contours of the mosaic or other design in such a manner that when the tiles are assembled the joints occupy various directions, so that the eye cannot distinguish them from the contours formed upon the plane surface of the tiles.

In the accompanying drawings a method of carrying my invention into practice is illustrated by way of-example.

Figure 1 shows four tiles intended to enter into the composition of an imitation mosaic pavement. Fig. .2 shows the variation of my device, displaying the tiles with the irregular-shaped bases.

As shown in the drawings, the tiles on b c (1 instead of being formed with regular edges in the ordinary manner are formed with edges e, which follow the contours of the do; signs formed upon the surface of the tiles. These sides consequently present projections f and indentations g,which when the tiles are assembled produce a mathematically regular and perfect fit. I

It will readily be understood without further explanation that under these conditions the joints are not distinguishable from the contours of the designs formed upon the surface of the tiles and that by means of tiles of this kind a perfect design may be obtained, the appearance of which is in no wise disfigured by the'joints of the various tiles constituting the pavement.

My method. of manufacturing tiles may be varied to some extent without departing from the spirit of my invention. For example, irregular-shaped tiles may be formed of a homogeneous material having figures or designs of one or more colors incrusted upon their surfaces, and these may be fitted to-.

gether as contemplated in my method in any desired arrangement.

Another variation contemplated by my invention is to form the base of the tile of any suitable material and to place upon this base, so as to completely cover the same and to coufo m to its contour, the fragments of different colors and difierent substances suitablefor a mosaic work, as marble, asphalt, or metal pieces. These base-pieces are then put together as with my first-described tiles, otheprojections of one base engagin g withthe recesses of the adjacent ones.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. A device of the type set forth comprising'a plurality of tiles, each provided with edges outwardly extending in various directions and irregular recesses formed between the outwardly-extending portions, said tiles 1 sellated work or mosaic the combination of an irregular-shaped base with a plurality of irregular-shaped pieces carried by said base and so arranged that they completely cover said base while rigidly following its contour substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 24th day of March, 1902.

ADOLPHE PICHA.
